Argentina is known for its beef. Fortunately, there is also really good Kosher beef. There is also Kosher McDonald's.Although Kosher McDonald's is exciting, we also went to the best (according to everyone in shul) kosher steak restaurant in Buenos Aires. We ordered appetizers, tons of steak and ribs, drinks, and just about every dessert on the menu. As you can see from the third photo, the total bill was $170.The thing is, the $ sign means "Argentine Pesos" in Argentina. That means, that for a very large meal, at the best kosher steakhouse in Argentina, it costs around 14 US Dollars a person. Also, you may notice in the pictures that there are no steak knives. That's because the steak was so soft that the standard issue restaurant knives were perfectly suited to cutting.

And now, the moment you've all been waiting for... this is the purpose of the mysterious bathroom implement:Aryeh was almost right. It is a sort of soap dispenser. Except that it holds a blob of hard soap that everyone shares.

This is a first for me; I don’t have anything to post about. So I will post about the AIAA airplane. As I have said I am the co-design team leader for the AIAA, and as such I will give you a quick update. The team has chosen a wing and all the other bits that goes with it, so all we need to do now is some fine tuning of the design. That’s all, sorry but I really don’t have anything interesting to talk about. Happy winter break, or for those of you who go to yeshivas happy exams.

A freind of mine's dad from Uni is an MP. Here I am shaking hands with him, Ian Cawsey (he debates in the house of commons and is part of Tony Blair's party). He was extremely nice and very funny without the creepily smooth feel you get from American politicians. He gave me and another mutual freind a tour of Parliament, stopping occasionally to say hi/ introduce us to his MP/ Lord friends.

We went in the back non-touristy way passing the MP's cubbies "like in grammar school," with name tags and everything. The difference being the little red ribbons which are to hang their swords on (zoom in to see them).

We weren't allowed to take photos at all except for in this hall: built in 1097, the roof is so old that they found some raquet balls stuck in the ceiling from Henry VIII.

find out more about this possibly coolest workplace ever here, but the bottom line is if you live near Grimsby then vote Cawsey!

Am really tired. Have been traveling by bus, plane, car, foot for way too long. But I'm back in the good ol' Estados Unidos. Firstly, I fixed the pictures from last week's post.I'll have a more comprehensive post next week, but for now, can anyone guess what the purpose of this mysterious bathroom implement is?Answers next week.

As we all go about our holiday shopping, for Chanukah, for Christmas, for Kwanza, for the Winter Solstice, for New Years, and for the Evil Chipmunk, we sometimes forget what the season is really about. Some people will tell you that it is the season of giving, of caring, and of jolliness, I am here to tell you otherwise. Every year as the holiday season rolls around so does the lovely holiday of Final Exams. Now some of you might say “but Final Exams isn’t a holiday”, well you are wrong. They come out about the same time of every year just like other holidays and there is joyous celebration caused by them (when they end). Like other holidays Final Exams causes much preparation even to the point of people staying up all night to be ready for the holiday, I can vouch for this because when my friends and I went to the Rutgers Busch campus dinning hall at midnight for the early breakfast the place was packed. So as you can see you should also give presents to weary college students after they have completed all their finals. I would like to wish everyone very happy holidays, a merry Final Exams, and to remind you to beware of the evil chipmunks.

I believe that Jonathan/Yoni will not be posting today.From talking to him Saturday night he mentioned that he probably wouldn’t have internet access, the reason he gave me was that his semester had ended, but that they didn’t have exams until after winter break, while those of us in the country of the United States have exams this week.Unfortunately I was not expecting to post anything today and therefore don’t have anything that’s exiting or interesting to tell you about.However, for the record I have found out that the method of integration I talked about last post is called Tabular Integration by Parts.The following is in fact rather old news, at least for those of us who are geeks, so if you have never seen this enjoy if you have enjoy it again.

Aoccdrnigto a rscheearch at Cmabrigde Uinervtisy,

it deosn't mttaer in waht oredr theltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsatltteer be in the rghit pclae. The rset can be a taotl mses and you can sitllraed it wouthit a porbelm.

Tihs is bcuseae the huamn mnid deos not raed erveylteter by istlef, but the wrod as a wlohe. Amzanig huh? yaeh and I awlyastghuhot slpeling was ipmorantt! if

However, I will point out that this only works if you know the word in question, this isn’t mentioned in the text. For example “eoxetpneaormus” is a word you might have heard of however “pneumonoultramicroscopicsilicovolcanoconiosis” this you might not know. I am 100 percent sure that you will never have seen this “hilrcibottaotndiianiuuifbis”.

I am currently in Mar Del Plata, Argentina attending a physics conference (if you are just joining our story in progress, see previous blog posts). Among the various attractions here are the sea lions which live in an area near the docks. There is a special sea lion wildlife preserve there. Or something. Here are some pictures of the sea lions:

This one was roaring.

Dweeee.....

After seeing them in the wild I understand why they're called "lions."The thing is, that when I said "near the docks" I actually meant "in the middle of the docks." Although the previous pictures made the lobos look all natural, they were on a teeny bit of rocks surrounded by concrete, rusting metal, and other natural niceties. Here is the second half of the colony of sea lions, sitting on a rusting half-sunk ship:And here are some sea lions inside a large industrial area in the docks. This was a few meters away from the other sea lion area. (Yes, the ones in the picture are alive.)

Here are a few assorted pictures of functioning cars that people drive around here.Check out the high-tech parking brake:

Standard method of integration by parts is shown in this image (I only show (u) and (dv) for the first time I do the integration by parts).

If you have no idea of what you read you either have never taken Calc II or don’t remember it. However if you know what you are looking at you will see that we just did integration by part four times in this problem which in this problem took quite a lot of time. Now as an engineer I felt there must be an easier way to do it. One of my friends gave me a method of integration by parts that was show to him by his high school Calc teacher, observe.

If what I am doing here is not clear here is an explanation. You choose your (u) and (dv) the same as you used to do, you then derivate the left column (u) until you reach zero. Then you integrate the right column until you have the same number of rows in both columns. Then diagonally cross over the first value of (u) to the second value of (dv) then add them all together. The signs as show alternate from positive to negative for each pair, starting at positive for the first pair.

As you can see we got the same answer using both methods, but the second is much faster than the first especially if we where to have to do integration by parts more times, such as if our function would be x^10sin(x). We would have to do integration by parts 10 times, or just use the quick trick I just showed you.

I got some publicity lately for my YouTube paternoster video with the vBlog RocketBoom linking to it here. (It now has over 1,000 views, not a lot for a youtube video, but a lot for one of mine). Some people left comments about it on rocketboom like this guy:

. . . Paternoster . . . meant our father. Apparently, as the lift became popular in Europe, plenty of people started saying quick silent prayers before attempting to use the seemingly dangerous device. The name stuck, and thus the "Cyclical Elevator" was pretty much dropped.

And this other guy:

There was a paternoster at the University I went to (DeMontfort University), also in Leicester.Rarely running due to people going "over-the-top" I had to climb 7-10 flights of stairs to get to my classes. Great idea if they worked.Maybe spikes at the top would be an idea?

It probably didn't work at DeMontfort Uni because they're not as good a Uni as Leicester, clearly we are smart enough to keep ours running almost all the time. Anyway, careful not to take any rubbish bins on board or it could decapitate you as shown in the following Swedish diagram.

Over the course of last year I was doing a rather cool experiment in YU for an Experimental Physics course. I built a macroscopic tool for one-dimensional phonon simulation. This involved hanging lots of (23) steel cubes (in prototypes they were balls) from long strings, vibrating them at different frequencies, and then measuring the amplitude and phase of the vibration of the final block.I will be presenting the results of this experiment (in the form of a poster) at the PASI conference that I'll be attending next week in Argentina.

You can download a (113kb) PDF of this poster here [pdf], if you want to be able to actually read what's there.

The day after Thanksgiving I went and saw the new James Bond Film Casino Royal. Do not fear I will not ruin the movie for you or anything. For those of you who have never seen a Bond film they traditionally start with some kind of action intense sequence followed by the classic gun barrel view of Bond, he turns and shoot and the camera goes red and falls to the floor. After this is a cartoon type thing with film credits and that particular movies theme song. In this movie the cartoon involved lots of spades, and hearts (card suits) doing things. The main theme however was Mandelbrot fractals using the spades and hearts images. I was definitely the only person in the theater who noticed it.

We learned in Lesson 1 on British Signage the marks for a railway station. This week we find learn about signs on the rare Motorways of England. Motorways are the highest class of road and they are the only roads in all of England without any roundabouts.

This sign alerts drivers to a fancy merge where two roads of 3 and 2 lanes merge to become a 4 lane motorway.

Often the signs here are very precise, for example this sign is for pedestrians, it means there are absolutely no picnics allowed on this spot, not even with salt and pepper shakers.

While at IKEA a while ago, we purchased two "CHARM" funnels for very cheap. It seems that you get what you pay for.As you can see, the slope of the funnel wall approaches zero as you reach the bottom hole. This means that the stuff you are trying to get to drain down the hole is essentially heading sideways, and must change direction very significantly in order to fall directly down the hole.

This fairly idiotic funnel design got me thinking: What is the optimal curve for a funnel's walls? Unfortunately, I've been incredibly busy recently, and have not had a chance to really work on this problem myself. However, this is an opportunity for another Lansey Brothers' Blog Contest! I am interested to find out what you, dear reader, think is the optimal curve. In some way, it should be a function of D (diameter of mouth), d (diameter of spout), and h (height of funnel), which should probably be order D, and where clearly d<D.

So if people can work this, and email me their solutions (MS Word or PDF form, with a copyright to themselves on it), I'll make a post in the future with a summary of the solutions, and my favorite. Please email solutions to .

It seems to me that I am the only Lansey Brother who hasn’t posted pictures of where he goes to school (of course he has posted pictures from school but we won’t talk about those).Considering that I have been going to Rutgers from almost three semesters now I have managed to never post any pictures.This is about to change.I hope you enjoy my pictures of Busch Campus.

Try to see if you can find the RAC (Rutgers Athletic Center) in this picture. Also in bottom left corner eletrical engineering building roof. In the middle of of picture you can see the roof of the Engineering Building specificly most of the Mechanical and Aerospace Department. Of course dont forget the Academic Services Buidlings below the curch spire type thing.

From the 7th floor window of Hill Center (Math) you can can see the materials science and engineering building (right side of picture). The Chemistry Buildings to the left of the materials building. Then the alcohol reaserch center to the left of that. On the middle of the left side of the picture you will of course see the Science and Engineering Resource Center. If you look real hard you can find the pointless modern art type sculpture showing shear force (its red).

A more artistic look at the materials building and of course the Busch campus Qaud.

On your left is the golf course and in the distance you can see the psychology and, pharmacy buildings, UMDNJ, and a bunch of other buildings. Also, some cars, some people, a bus stop, lots of trees, and a really small beach.

Now I have posted pictures of the non-radioactive, non-city college that a Lansey Brother goes to. Now it is time to post the funny/intresting pictures.

If you click the photo you will see that there is a great light on the bottom left that says "HELP IS ON THE WAY" they should have a light next to it that says "WE HAVE CHOSEN TO IGNORE YOUR ALARM CALL BUTTON BECAUSE WE DON'T FEEL LIKE HELPING YOU"I couldn't not take this picture, I saw this while I was trying to get onto the Hill Center roof to get better pictures. You are looking down eight flights of very cool steps.

While conducting research in exotic overseas urinals, I came across a rare Paternoster at the University of Leicester. This happens to me my first shot at a YouTube style video so please rate it highly (here) if you like it!

Aryeh's field guide to the diversity of American Urinal (americanas urinalas), including related species in the porcelainas americanas family, although very thorough (he included the extremely rare horned urinal [urinalas cornu]) missed a few species. Specifically, urinalas scaphium, which can be found in the Yeshiva University's Pollack Library and Belfer Hall.This species appears with both automatic (in the library) and manual (in Belfer) flush traits. While it is unclear which of these is the dominant trait, the automatic flush variety are notoriosly moody, and tend to flush with little provocation, so one would hope that it is reccesive. Additionally, unlike its cousins which regularly maintain a small amount of water, this species of Urinal maintains a large volume of water. For these reasons, it is suggested that perhaps this species is the missing link between the larger toilet bowls (americanas standardium) and urinals.

Although Aryeh suspects that sinks (cleanlinus basinium) have a symbiotic relationship with Urinals, it is widely accepted that urinal cakes (crustum urinalas) do in fact maintain this symbiotic relationship.Finally, there is a species of Urinal that has proliferated in recent years which uses no water at all - the Waterless Urinal (urinalas aqualess) -which lives in more arid climates. However many experts suspect that this species is the result of genetic engineering, not a recently discovered native urinal.

On a couple of occasions Eli has pointed out that I get to post on all the holidays that come along.Today will be no exception, this might confuse you slightly as today is Tuesday and Thanksgiving isn’t until Thursday, which as we know is Eli’s day to post.However due to Rutgers creative scheduling today is Thursday and tomorrow is Friday, so I still have managed to post on Thanksgiving.As such, I would like to wish everyone a very happy Turkey Day.

Now that I have finished with the introduction part of this post I can now get to the body.I do not recall precisely how this came up in conversation, but my mother expressed confusion about the nature of the urinals in men’s bathrooms.She had been under the impression that Urinals were simply long trough like apparatuses. I will now attempt to clarify this issue. To do this I walked around the Rutgers campus with a hidden camera and got the insiders view of the men’s restrooms urinals.Now we shall embark on the great urban safari, soon we shall see some urinals in their native habitats.

This is a relativly standard breed of Urinal, however notice the intresting horn. I have only observed this characteristic on Urinals native to the 7th floor of the Hill Center.

Here is a close up of the unusual horn.

This here is an very intresting group three Urinals of diffrent sub-species. I was lucky enough to come across this in the Physics Lecture Hall.

Here are five identical Urinals, now this is a very strange grouping as I have only once seen or heard anyone is this region (the one time occured when I was taking this picture).

These are in fact not a Urinals. They are Sinks they are rather close relitives of the Urinal and you will often see them grouped near each other. My current reasearch would indicate that they have a symbiotic relationship.

Train StationThe symbol for a train station is circled in blue. This can appear on maps road-signs or on the station itself. It was chosen very soon after the invention of railroads to remind engineers to drive on the left side of the railroad.

So I want to take a picture of this funny symbol thats in a completely random spot of road outside the station and these two drunken weirdos stumble out of a pub. When the man who looks like zorro insisted I take a photo, who am I to say no? In Newark that only happens right before they run off with your camera. (10 points if you know what the red thing the fat one is wearing on his chest).
